Nanoparticles have a wide range of applications in our day to day life. Different methods of biological synthesis of
metallic nanoparticles are being employed worldwide and many researches are still underway as a part of improvement strategy.
Various microorganisms and abundant plant materials are used for this purpose. A chemical reducing agent is often replaced by
the extracts of plants and microorganisms during the biosynthesis phenomena of nanoparticles which have proven to be novel
approach in recent years.
